I don't like when static zaps me from keyboard or mouse or some random metallic part of casing, so I often touch some grounding before resuming working with the computer.

However, it often disrupts it's function: if I discharge into outer ground in VGA output, I get hub 1-0:1.0: port 2 disabled by hub (EMI?), re-enabling... and USB reconnect. If I discharge on USB extender outer ground, USB devices tend to glitch.

How it's better to resume working on computer if you know that you are charged?

Just how often does a static charge zap you for it to make a difference? I can't remember the last time it happened to me, therefore this question. – Rook Mar 9 '11 at 18:42

Go touch a door knob to discharge the static into the doorknob instead of your PC. – Breakthrough Mar 9 '11 at 18:44

Regularly (especially at work). I've got used to grasp keys (or other metallic thing) and touch it some grounded thing before touching doorhandles, windowhandles or computer. – Vi. Mar 9 '11 at 18:45
Breakthrough, The charge acculumated when I go from doorknob to computer can be uncomfortable. Also I don't want to go somewhere every time. – Vi. Mar 9 '11 at 18:46
@Vi - Well, have you ever wondered what you're doing that could cause the static to build in ya? – Rook Mar 9 '11 at 18:47

None.

Unlike desktop computers, laptops aren't grounded and there are no parts which are 100% safe.

As for USB, usually there are static protection chips installed in computers which are supposed to prevent destruction of the port, but they aren't meant to be shocked all the time.

As far as I know, but I could be wrong, in normal operation USB ports are components which are most exposed to static electricity and they should have best protection. Another part which should also be protected is the 8P8C network jack.

So safest way would be to touch outer shield is USB cable. Since it causes glitches on the port, the amount of electricity is considerable and will probably soon render ports unusable.

I know you specifically asked NOT to receive adivce on how to prevent static buildup, but I feel I must mention anti-static mats. Basically it's mat which plugs into something grounded such as ground pin on a power outlet. Place the laptop on top of one of these and discharge yourself by touching the mat before touching the laptop. Its advantage over wristband is that you don't have to physically ground yourself and are free to move. They can be purchased for $10 to $30 depending on the size an are definitely much cheaper than repairs of damage caused by static electricity to the computer.
